3.1 Analog Outputs

The output pins are low-impedance voltage sources.

3.2 Analog Inputs

The non-inverting and inverting inputs are

high-impedance CMOS inputs with low bias currents.

3.3 CS Digital Input

This is a CMOS, Schmitt-triggered input that places the

part into a low power mode of operation.

3.4 Power Supply Pins

The positive power supply pin (VDD) is 1.4V to 6.0V

higher than the negative power supply pin (VSS). For

normal operation, the other pins are at voltages

between VSS and VDD.

Typically, these parts are used in a single (positive)

supply configuration. In this case, VSS is connected to

ground and VDD is connected to the supply. VDD will

need bypass capacitors.
